Trying to build ntfs3g fails if the GIT version of fuse is installed.

sys-fs/ntfs3g-2012.1.15-r1 fails to compile due to
x86_64-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I.. -DFUSE_USE_VERSION=26 -D_FILE_OFFSET_BITS=64 -I/usr/include/fuse -I../include/ntfs-3g -mtune=native -O2 -msse3 -pipe -Wall -c -o ntfs_3g-ntfs-3g_common.o `test -f 'ntfs-3g_common.c' || echo './'`ntfs-3g_common.c
ntfs-3g.c:3256:2: error: unknown field 'flag_utime_omit_ok' specified in initializer


The field flag_utime_omit_ok is (only) defined in
include/fuse-lite/fuse.h

Should this be included in ntfs-3g.c ?

What's the right fix?

Thanks,
Helmut.

Hi,


This field is needed for setting timestamps with a microsecond resolution with the high level fuse interface, it was proposed by the fuse developers.

It has apparently not yet been included in a release version. The code in ntfs-3g assumes it will be included in fuse 2.9, but if you get an error, a new fuse version is being prepared without the feature (or the feature is implemented differently).


This is for use with the internal fuse-lite library (just ./configure with option --with-fuse=internal with Linux only). This library provides all the features used by ntfs-3g.

Other possibilities :

- Apply the fuse patch to the git version (see http://article.gmane.org/gmane.comp.fil ... devel/8592)
- Patch ntfs-3g.c to not use timestamps with subsecond resolution (just comment the line for flag_utime_omit_ok initialization), you still can get subsecond resolution by using lowntfs-3g instead of ntfs-3g.

Note : this has recently been discussed on the fuse developers list, awaiting a reply from the fuse project for defining how ntfs-3g should adapt.

Hi,


In git, I did not find any version of fuse beyond 2.8, though there is a place holder for 2.9. The fuse version is defined in fuse_common.h
Can you clarify under which conditions you got an error (what were your options to ./configure, where did you get fuse_common.h from) ?

Regards

Jean-Pierre

My fuse version is from yesterday (I'm working on a GenToo system)

/usr/include/fuse/fuse_common.h

has

/** Major version of FUSE library interface */
#define FUSE_MAJOR_VERSION 2

/** Minor version of FUSE library interface */
#define FUSE_MINOR_VERSION 9

And I've searched all of /usr/include/fuse/**/* but flag_utime_omit_ok isn't contained in any file.

Helmut.

Hi,


So GenToo must be ahead of the fuse git...

On the fuse project git (http://fuse.git.sourceforge.net/git/git ... ;a=summary), I see :

The fuse_2_9_start is a placeholder for features which cannot be released as 2.8, and the fuse_common.h it contains is marked as 2.8, so your 2.9 version must be a non-official one, not issued by the fuse project.

Until the matter is resolved, you can use one of the workarounds defined in my previous post.

Also tell me what timestamp resolution you get when doing "touch an-existing-file", in case another strategy has been defined in this fuse 2.9.

Hi Jean-Pierre, I don't think so.
It's not Gentoo package, but I have created a so-called ebuild file myself.
It contains:
EGIT_REPO_URI="git://fuse.git.sourceforge.net/gitroot/fuse/fuse"

and that's the only source!

Helmut.

Hi again,


Ok, so you are using the latest state, which is not a stable version yet.

This at least made me aware that utimensat(2) might not be fully implemented in fuse 2.9, unless it is implemented in a way different from what I expected.
